COOKING-LAMP.

SPECIFICATION forming part of Letters Patent No. 553,686, dated January 28, 1896.

Application filed June 10,1895. flerial No. 552,246. (No model) To (all whom it may concern:

Be it known that I, YVILLIAM A. PENFIELD, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Cooking-Lamps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a plan view of a lamp constructed in accordance with my invention; Fig. 2, a view thereof in side elevation; Fig. 3, a view in vertical central section; Fig. 4, a detached view in side elevation of the wick-holder.

My invention relates to an improvement in cooking-lamps of that class which employ asbestos or equivalent wicks, and which are primarily designed to be used in conjunction with ch afing-dishes or small hot-water kettles such as are used in the service of afternoon tea, the object being to produce, at a low cost for manufacture, a simple, conveuient, durable and effective lamp.

lVith these ends in view my invention consists in a cooking-lamp having certain details of construction, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention as herein shown I employ a vertically-arranged tubular wick-holder A, in which I locate a filling or wick of asbestos B or other suitable ma terial. The lower end of this wickholder is set into a step or recess C, formed in the fount or' bowl C, of larger diameter than the said wick-holder, whereby the lower end of the wick-holder is held against lateral displacement. The annular chamber C formed between the wickholder and the bowl C is designed to receive the burning-fluid. As herein shown, the burning-fluid flows inward to the wick through a circular band of vertical passages a, formed in the bottom of the wick-holder, which may be otherwise adapted to permit the oil to flow inward through it to the wick from the annular chamber C Thus, if desired, the wick-holder may be made imperforate throughout its length, but supported within the bowl, so that there will be a space under its lower edge, or the wick-h older might be provided with openings constructed and arranged otherwise than the passages. The upper end of the wick-holder extends considerably above the upper edge of the bowl, and is covered and closed by means of a disk D of wire-netting, which is bent downward over the upper edge of the wick-holder so as to be confined in place by an annular sheetmetal ring E, the lower edge of which is furnished with a flange e, which is formed, as herein shown, over the extreme upper edge of the bowl. The upper edge of the said ring is constructed with a downwardly-inclined inwardly-projeeting annular deflecting-flange 6, between the inner edge of which and the disk D of netting there is a narrow annular space 6 as shown in Fig. 3. The outer edge of the said flange e merges into a verticallyarranged band or fillet 6 forming a part of the ring E, and containingahorizontal row of air-inlet openings (2", also shown in the same figure.

In the use of my improved device, burningfluid, such as alcohol, is poured upon that portion of the wire-netting D which is exposed through the central opening of the ring E. Some of the fluid will pass through the netting and be absorbed by the wick, but as the wick is dense and will absorb the burning-fluid only very slowly the main bulk of it flows outward over the netting and through the narrow annular space E into the chamber C of the bowl. I am thus enabled to pour the burning-fluid freely into the lamp, as the space E makes ample provision for its free passage into the bowl, from which it is taken up by the wick as fast as needed.

Then the lamp is lighted, the flame is sus tained by air drawn in through the perforations 6 and thence deflected by the deflecting-flange 6 onto the flame, through the an nular passage 6 in the form of a cone, which strikes the flame obliquely, and has the effect of drawing the same to a point, which is the result I desire to secure, whereby I obtain a heating-flame of great intensity.

It is apparent that in carrying out my in vention some changes in the construction shown and described may be made, and I would have it understood that I do not limit myself to the exact form shown, but hold myself at liberty to make sucha-lterations as fairly fall within the spirit and scope of my invention. Thus the particular form ofthe bowl and ring might be considerably modified.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cooking-lamp, the combination with a bowl, of a vertically arranged wick-holder located therein, with a space between it and the same, a wire netting applied to the upper end of the wick-holder, and a ring applied to the upper edge of the bowl, and comprising an inwardly extending, annular deflectingflange between which and the wire netting a narrow, annular passage is formed, substantially as described.

2. Inacooking-lamp, the combination with the bowl thereof, of a wick-holder located therein with a space between it and the same, a netting of wire applied to the upper end of the wick-holder, and a ring secured to the bowl, and comprising an inwardly extending, downwardly inelin ed annular deflecting flange between the edge of which and the netting a narrow annular passage is formed, and also containing a band of perforations which admit air to the said passage, substantially as described.

3. In a eooking-lamp, the combination with the bowl thereof, of a tubular wick-holder smaller in diameter than the bowl, having its lower end set into a recess formed in the lower portion thereof, and its upper portion extended above the upper edge thereof, a netting of wire applied to the upper end of the wick-holder, and a ring applied to the bowl,

constructed with perforations for the inlet of air, and provided with an inwardly extending annular deflecting flange between the inner edge of which and the wire netting there is formed an annular passage, throughwhich air is projected obliquely upon the flame, substantially as described.

at. In a cooking lamp, the combination with the bowl thereof, of a tubular wick-holder located therein with a fluid containing-space between it and the same, and constructed with perforations to permit fluid to pass into the wick, a netting of wire applied to the upper end of the wick-holder, and a ring applied to the bowl and coacting with the wire to deflect air obliquely upon the flame, substantially as described.

5. In a cooking-lamp, the combination with the bowl thereof, of a wick-holder therein with a fluid-containing space between it and the same, and from which there is access for the fluid to the wick contained within the said holder, a netting of wire applied directly to the upper end of the holder, and a ring applied to the upper portion of the bowl, and constructed with a central opening exposing that portion of the netting resting upon the upper end of the holder, substantially as de scribed.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
